It's actually from a comic book "Elmer", and it actually is about ethics!
"Elmer is a window into a world where chickens have suddenly acquired the intelligence and consciousness of humans, where they can now consider themselves a race no different than browns, black, or whites. Recognizing themselves to be sentient, the inexplicably evolved chickens push to attain rights for themselves as the newest members of the human race."

Is that from Elmer?
Have you Elmer by Garry Alanguilan? It deals with this issue directly. Even uses chickens as the animal in question.
Check out Elmer. Chock-full of social commentary, mostly dealing with prejudice.
I think this would be a good time to recommend the book Elmer. Seriously. Written and drawn by creepy smile guy
